Abstract:
Objective To explore the influence of Hedysari radix concentrations fluid (HRCF) on learning and memory and its effect on cerebral monoamine neurotransmitters in senescence accelerated mice. Methods The senescence accelerated mice were randomly divided into the senescence accelerated mouse/resistance 1 (SAMR1) control group, senescence accelerated mouse/prone-8 (SAMP8) model group, HRCF treatment group and aricept treatment group. After 3 months of intragastrical treatment, the learning and memory ability changes and content of norepinephrine, dopamine, 5-hydroxytryptamine and 5-hydroxyindoleacetic acid were detected respectively using Morris water maze and high performance liquid chromatography. Results In the model group, the hidden platform test indicated that the latency to find the hidden platform was remarkably prolonged, and the content of norepinephrine, dopamine, 5-hydroxytryptamine as well as 5-hydroxyindoleacetic acid were significantly reduced (P<0.01). Compared with the model group, the latency of hidden platform test was remarkably shortened (P<0.05) and the content of norepinephrine, dopamine, 5-hydroxytryptamine as well as 5-hydroxyindoleacetic acid were obviously increased in HRCF treatment group (P<0.01). Conclusion HRCF could improve learning and memory ability of SAMP8 and the influence may related to increasing the content of cerebral monoamine neurotransmitters.
